Please help with these questions 1. Methane (CH4) burns in air to form carbon dioxide and water as shown below. CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(l) If a sample of methane occupies 802. mL at 3.23 atm, what pressure (in atm) of oxygen gas with the same temperature and volume is required to complete the reaction? 2. Consider the reaction between hydrogen gas and nitrogen gas to form ammonia: 3 H2(g) + N2(g) → 2 NH3(g). What...
We can determine the molecular mass of air by considering nitrogen (N2), oxygen (O2) and argon (Ar) make up 78%, 21% and 1% of the atmosphere. The atomic masses of nitrogen, oxygen and argon are 14, 16, 40 grams/mole. Compute the molecular mass of air.
An air sample in the lungs contains oxygen at 98 mmHg, nitrogen at 568 mmHg, carbon dioxide at 32 mmHg, and water vapor at 51 mmHg. What is the total pressure, in atmospheres, exerted by the gas mixture?
